Beer Mortar Arm Pack – Multi-Height Compatibility Upgrade Kit

Product Description:

Fine-tune your mortar. Maximise compatibility. Get the perfect launch.

Bottle heights vary far more than most people realise. Even within the same country or brand, small differences in height and neck geometry can affect performance. The Beer Mortar Arm Pack allows you to precisely match your mortar to the bottles you’re using.

This kit includes:

• 1 Longer Arm – Designed for taller bottles that sit deeper in the tube.

• 2 Shorter Arms – Ideal for shorter bottles that require earlier engagement.

Your mortar comes fitted with our most universal arm, but if you’re switching between brands, using imports, or simply want the strongest cap launch possible, this pack gives you the ability to dial it in properly.

Why Arm Length Matters

The relationship between bottle height and trigger timing determines how efficiently the cap is removed and launched. Even a few millimetres difference can change performance dramatically. The Arm Pack lets you adjust that geometry for:

• US 12oz bottles

• European 330ml bottles

• Short stubbies

• Taller long-necks

• Regional bottle variations

Compatible with all current 51mm Beer Mortar models
Quick to swap. No tools required.

If you want consistent performance across different beers, this is the upgrade that makes the difference.
